Was trying to work up a progression table based off the Races of the Wild progression for Straight Rakshasa, but more martial/rogue, i.e. a Naztharune (MM3). I's there anything like this in existence, or anybody have something like this?

Or would it better off to go straight Rakshasa and multi class into swordsage/duskblade (or something more combat focused), counting on the sorcerer levels to give some helpful buffing?

Finally, in a non-optimized CL-10 party, would this as a PC be underpowered?
